Island Lake, Ill., assignors to Illinois Tool Works Inc., Chicago, Ill., a corporation of Delaware Filed Jan. 22, 1969, Ser. No. 793,122 Int. Cl. F16b 1/00 U.S. Cl. 287-189.35 Claims ABSTRACT OF THE DISCLOSURE SUMMARY OF THE DISCLOSURE This invention relates to improvements in clip means for securing together lapping edge portions of decking without prior preparation of the decking material and mounting thereon insulation or like material with nothing showing at the underside of the decking after installation.

An object of the invention is to provide a clip element with recess means for interlocking with one decking edge portion and sharpened cutting edges for engaging upward wall portions betweenv which the adjacent lapping decking edge portion extends.

Another object of the invention is to provide a clip element of the above type which is rotatable into position for securing together the lapping decking edge portions, and to provide a cooperating T-shaped holddown clip for interlocking engagement with the installed clip element in securing insulation or like material to the decking.

A further object of the invention is to provide a clip assembly of the above type wherein the T-shaped holddown clip includes laterally extending spaced arms to interlock with the recess means on the clip element for holding the insulation or like material to the decking.

The above and other objects of the invention will in part be obvious and will be hereinafter more fully pointed out.

As shown in FIGURE l, roof purlins 10 are illustrated in the form of I beams spaced apart a suitable distance,

"ice

such as eight-foot spans and on which corrugated decking material 12, 12a is supported. The longitudinal lapped edge portions 14, 16 along the valleys of adjacent corrugations of the decking 12, 12a are secured together by deck clips 18 spaced therealong at suitable intervals and which are rotatable to fastening position as will be hereinafter pointed out. The clips are preferably formed of hardened and tempered steel and designed to support at least a 200 pound load along the connected edges of the decking between spans.

Referring to FIGURES 2, 2A and 3, each clip 18 is illustrated as generally rectangular in shape and platelike but other configurations may be employed. Each clip includes a central body portion 20 having struck therefrom a tab 22 folded over to parallel the adjacent surface of the body portion 20 forming a recess means and remaining integrally attached thereto by a strap portion 24. The spacing between the tab 22 and the adjacent body portion is such as to snugly receive the decking edge 16 therebetween. The tab is illustrated as substantially square with an upwardly bent camming corner 22a and is intentionally out-of-round to leave a similarly shaped opening 26 for receiving a similarly shaped tool to rotate the clip into fastening position as will be pointed out, and for this purpose the body portion 20 is offset upwardly from the edge portions 28, 28a, and 30, 30a thereof at least in the region of the opening 26 to allow room for tool insertion. The transverse or shorter edge portions 28, 28a of the body are bevelled to provide sharp biting edges 29, 29a to dig into the upwardly extending wall portions 14a, 14b of the decking edge 14. The longitudinal edge portions 30, 30a of the body terminate in stop projections 31, 31a, respectively.

In mounting each clip for assembly with the decking edges 14, 16, it is placed in the dotted line position of FIGURE 2 resting on the decking edge 14 between the wall portion 14a and the edge of the decking edge portion 16. Then a square ended tool is inserted in the opening 26 by a standing workman and rotated to the full line position of FIGURE 2. During this rotation of the clip, the camming corner 22a will serve as a guide for positioning the decking edge portion 16 between the tab 22 and the adjacent surface of the body 20 as shown in FIGURE 3. Also during this rotation of the clip, the curvature of the biting edges 29, 29a is such that they have a camming action to progressively cut into the decking wall portions 14, 14a and provide initial purchase for the clip in holding the decking edge portions 14, 16 as they are relatively drawn together in cooperation with the recess means to closely spaced parallelism with nothing showing below. The stop projection 31, 31a will abut adjacent surfaces of upwardly extending decking walls 14a, 14b to prevent over-camming of the tab 22 and excessive cutting by the biting edges 29, 29a.

When the mid-span clip 18 is positioned as above described, a T-shaped stirrup-like clip 36 or hold-down may be applied thereto for holding insulation material 38 against the decking, as shown in FIGURE 3, and reference is made to FIGURES 4, 5 and 6 for a description of the hold-down clip which includes a head portion 40 consisting of a horizontal plate portion 42 and a pair of horizontal arms 44, 44a struck from an upper shank portion 46 which, in turn, terminates in a lower platelike shank portion 48. The lower edge of the plate por- -tion -48 terminates in a lateral stirrup-like clip formation including a lower right-angled arm portion 50 having a downwardly curved camming end 50a and a pair of upper right-angled side arm portions 52, 52a, forming with the arm portion 50, a laterally opening recess. Within the ends of the inner edges of the arms 52, 52a, there are notches 53, 53a. Lateral resiliency is afforded the arms 52, 52a by slots 54, 54a along the plate portion 48.

In applying the T-clip to the clip 18, the arm portion 50 is passed into the opening 26 and the shank is then forced laterally to receive the adjacent wall portion of the clip body 20 in the region of the strap 24 between the arm 50- and the arm portions 52, 52a. During this lateral movement of the arms, the arms 52, 52a will be spread by engagement of the cam surfaces 55, 55a, respectively, thereon with the adjacent edges of the strap portion 24 of the clip 20 and the arms will later return to normal positions with the adjacent edges of the strap portion 24 trapped within the notches 53, 53a, thus mounting the T-clip 35 to the clip 18 for hold down engagement of the head portion 40 with the insulation material which is thus held against the decking 12, 12a, etc. While the assembly of the T-clip 36 and clip 18 is shown along the area of securing together the decking edge portions 14, 16 in -FIGURE 3, it will be understood that the clip 18 may be mounted in other integral valley portions of the decking by biting engagement of the edges 29, 29a with the side walls of the corrugations and the T-clip assembled therewith for holding insulation ma terial along these areas. Release of the T-clip can be eifected by the access area between the arms 52, 52a above the arm 50 permitting entry of a tool for spreading the arms 52, 52a to clear the notches 53, 53a from engagement with the strap 24.
